I own the 715 for Glocks. All the standard frame 9mm, .40, and .357 Glocks will fit it. It works very well for me for both my 17 and 26. My main use for it, though, is not as an all-day holster, but as the ideal holster for those days when I know I will taking the holster off and on several times. For those who don't know this holster, it is an IWB, leather, with a strong clip. It is secure on the belt but still fairly easy to put on and take off. It is far more comfortable than most Kydex IWB holsters.
My only caution is that if you are sitting in odd positions it can sometimes tilt on you a little because it has only one point of attachment. I also have several other Don Hume holsters for Glocks, and all are good quality and heavy duty. They last forever. It is true that they are not as pretty as some others and are generally not lined.
